Welcome Aboard, Heather!
Please don't stress out about what night you will be wearing which outfit. As long as you have them all packed, you will be fine.
For sure, your first night onboard will be
cruise casual. This simply means that swimwear and tank tops are not allowed in the main dining rooms. You will also have a dining room schedule printed on your Key To The World card. Your dining room team can tell you which nights are coming up.
When sailing on a 7-Night sailing on the Disney Fantasy, you can expect one optional formal night and one optional semi-formal night, where your fellow cruisers will be dressed in everything from ball gowns and tuxedos (my dress of choice) to sundresses and polos with khakis. The choice is completely yours, which is why it is "optional". Whatever you are comfortable wearing, it is your choice.
Somewhere in the middle of your cruise, you will experience
Pirate Night. At this time, passengers young and old will be dressed in their pirate-y best (or worst!). This is my favorite night on my Disney Cruise Line vacations. We go all out and wear full pirate outfits! Be sure to catch the fireworks, too.
So, please, relax and get ready for one of the best vacations you have ever experienced! Each night, a Daily Navigator will be delivered to your room. This will have a schedule of the following days events, along with what the dress code for dinner is. You will most likely spend the majority of your days in your swimsuit, leaving the pool with just enough time to shower and change for dinner.
I hope this helps to ease your mind a bit. Have an amazing time on the Disney Fantasy in just a few days!
Happy Cruising, Tracy V.
